Fixed a performance issue with the Scene View in LOPs when displying large scenes.

Fixed incorrect behaviour in the USD Skin Import SOP and the Agent SOP's USD import mode, when importing a mesh that had skinning and blendshapes along with a non-identity skel:geomBindTransform matrix.

Fixed a bug in the multiik component removing the double transform when scaling the joints.

XPU: "hitPz" rayimport (camera-space depth) uses absolute distance and no longer allows negative distance. This also addresses illegal depth values in deep image output.

Fixed an issue with work items that depend on upstream items in a feedback block not cooking properly when a cook is triggered using the "Cook Work Item" context menu entry.

Fixed hcustom and the HDK Makefiles on Windows so that they add the HDK pythonX.Y include directory to the compiler's header search path. This fixes errors when compiling code that includes <UT/UT_PackageUtils.h> for example.

Floating windows no longer disappear when Houdini loses focus on macOS. This applies to windows that float on top when the General User Interface -> Keep Floating Windows on Top preference is checked on.

Fix potential .bgeo corruption when saving a mixture of float4 and float volume primitives.

PCA SOP will behave sensible with zero dimension input rather than potentially crashing.

Improve Volume Splice SOP with unequal tiles.

Improve Volume Splice SOPs behaviour with unequal tile sizes.

Fixed an issue with work items that have dependencies within their node not cooking when a cook is triggered using the "Cook Work Item" context menu entry.

Karma will now only print out the "non-indexed attribute" warning four times. When importing string attributes to USD, it's a good idea to import them as indexed attributes to save memory and resources. However, Karma will no longer fill the log with warnings about this optimization.

Fixed a bug in the Houdini embedded help browser where the browser's zoom factor resetted back to 1 whenever loading a new page.

Renamed RBD Car FollowPath SOP's "Wheel Spin" parameter to "Wheel Spin Scale" for clarity.

Added an option on the Edit Prototypes LOP to not author any composition arc on the selected prim(s). This lets you use this node to create a class prim structure at the destination of an existing inherit arc.

Attempt to improve the performance of the LOP viewport when interacting with handles.

Fixed a bug in motion paths on Abstract Controls that cause the entire path to be drawn, ignoring the values of the "Limit Frames" options.

Fixed a potential crash in the viewport when displaying an agent shape which contained packed primitives with a boneCapture attribute inside the packed geometry.

Add a name alias for the Attribute Adjust Tags for Attribute Adjust Array. In order to make it for the use case of tagging more discoverable in the tab menu.

Fixed a bug where shading normals erroneously used pre-displace normals for motion segments when a mesh has displacement shader and rendered with deformation blur. This bug was introduced in 20.5.305.

Fixed a "No active drawable selector available" python error in the Curve state when attempting to do a selection through the select icon on the left side of the viewport while in the curve state.

Changed default behavior of the Bright COP to leave the alpha channel untouched.

XPU: Fixed a bug in expanding a custom MaterialX node

Fixed a python error in the point weld state when attempting to weld to a point in a different node's geometry.
